Dissimilar welds close to the fusion boundary exhibit a variety of solidification microstructures that strongly impact their service behavior. Investigations were therefore undertaken clarify origins morphological and microstructural evolutions encountered in 18MND5/309L dissimilar joint produced by submerged arc welding, using combination characterizations, thermodynamic computations, modelling. An unexpected evolution was observed mode, from primary austenite towards ferrite with...
Hardening precipitation frequently occurs in Mg–rare earth (RE) alloys after heat treatment the 150–200°C range. Early stages of have been studied detail by transmission electron microscopy two Mg–RE (Mg–Y–Gd and Mg–Y–Nd). Two types structures may be involved sequence: a DO19 phase so-called orthorhombic β′ phase. The structural relationship between phases has established underaged overaged states from observations at peak ageing. We show that earliest precipitates play key role selection...
Minor addition of zirconium is common in polycrystalline nickel-based superalloys, where it believed that segregates at grain boundaries and contributes to increase the creep resistance. However, superalloys produced by additive manufacturing, may become detrimental as promotes hot-cracking during fabrication stage. Here, we clarify controversial role this element studying its distribution near atomic scale as-built heat-treated microstructures. In microstructure, almost exclusively found...
Flat duplex stainless steel acquires its characteristic banded microstructure during processing sequence, which ends with a final annealing step aimed at fine tuning the phase ratio to equal parts ferrite and austenite. Besides fraction, grain structures, shapes morphologies of both phases evolve too this step. In present, it was shown that recrystallization is mostly complete end heating equilibration shortly after. As consequence, chemical elastic driving forces are rapidly depleted while...
THOMSON-CSF is developing thinned CCDs for backside illumination which will provide high quantum efficiency the detection of UV, soft X-ray and electrons a few keV. The most critical stage process treatment devices : accumulation condition necessary to prevent recombination photoelectrons created near back surface. developed at involves shallow p+ implantation activated by laser annealing. Results obtained on frame-transfer (576 x 384 Pixels) are presented 50% 3500 Å (25°C) in excess 60%...
